Title: Method and device for mounting semiconductor chip
Inventor: FUNAKI TSUKIO
IPC: H01L21/60
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To prevent defective electric connection between a semiconductor chip and a mounted substrate in the flip-chip mounting using an anisotropic conducting film, and to improve production efficiency. SOLUTION: The following devices are provided. A heating block 5 heats and compresses every one semiconductor chip of four semiconductor chips 1 which are arranged on a mounted substrate 3 through an anisotropic conducting film 7, and has a flat compressing surface 5a having the same size as the semiconductor chip 1. A heating and supporting block 4 supports the mounted substrate 3 and can heat a chip mounting part 3d of one semiconductor chip 1, to which the mounted substrate 3 is thermally compressed. A nozzle 10 blows air 8 to a back surface 1b of the semiconductor chip 1 and cools the other semiconductor chip 1, which is not thermally compressed. A cooling block 11 cools the chip mounting part 3d at the mounting substrate 3 of the other semiconductor chip 1 from the side of the substrate back surface 3c.  The four semiconductor chips 1 are thermally compressed individually for every one semiconductor chip 1 on the mounting substrate 3.

Title: Connection method of pipe member
Inventor: SUEYOSHI HIROKI
IPC: F16L21/02
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To find coming off of a rubber ring during the connection of pipes and improve the workability and safety of piping by comparing an insertion pressure measured value which is measured at an insertion length position of an insertion port from an insertion end part with an insertion pressure set value which is set in advance at the insertion length position and stopping the insertion if a difference between two values is out of allowable range. SOLUTION: A pressure sensor 2 measures pressing force applied to a pipe member 6 from a pressing plate 12 and sends the results to a computing and processing part 4. A displaecment sensor 3 is provided on the opposite face to a pressing face of the pressing plate 12, measures a travel amount of the pressing plate 12, and sends the results to the computing and processing part 4. The computing and processing part 4 receives an instruction from an operation part 5 to send a signal for operation instruction to a pressing machine 1, compares an insertion pressure measured value which is fed from the pressure sensor 2 with an insertion length fed from the displacement sensor 3 and an insertion pressure set value which is set in advance at the position, and sends a stop signal, if a difference between them is out of a scope of allowance, to stop the feed pressing machine 1.  Consequently, it is possible to find coming off of a rubber ring during the connection without relying on visual inspection and shorten work period.

Abstract: PURPOSE: To enable to open an emergency door in a more reliable manner at the time when pressure loss is higher than a predetermined value, by controlling supply of compressed air to a locking means which is operated by compressed air from a compressor, by the output of a pressure detector.  
     CONSTITUTION: In case that pressure loss has become higher than a predetermined value (for instancem about 50mmH 2 O in case that only a filter is used) by reason of clogging of the filter disposed in inlet house 21, it is detected by pressure switch 23 and three-way valve 19 is shifted by the output signal of pressure switch 23. Resultantly, high-temperature compressed air is made to flow in the direction from A to C, and at the same time, pressure in cylinder 28 is lowered. Further, the force of spring 27 disposed in cylinder 28 is applied so that piston 26 is moved downward and comes out of recess 20c of door panel 20b. Therefore, door 20 is unlocked and the emergency door is opened, so that air is introduced from the door space.

Title: Fluid sealed type vibration proof supporting device
Inventor: TANABE MAMORU
IPC: F16F13/14
Filed: 1994-03-16
Abstract: PURPOSE:To improve the vibration proof performance in the medium and high frequency range by arranging a lump body keeping the constant space from a connecting band in an integrated manner with an orifice structural body on both sides of the connecting band. CONSTITUTION:When an outer cylinder 12 is fixed, and an inner cylinder 10 is connected to a vibrating body, the inner cylinder itself is vibrated by the vibration, and the volume in a main and a sub fluid chamber 20, 22 is changed to allow the fluid to move and the vibration to be damped. At the same time, the transmission of the vibration is also shut off by a rubber elastic cylinder 18. In the case of the excessive displacement, a lump body 32, a connecting band 36 and a bridge body 34 work as the respective stoppers. Because the space 48 is provided between the connecting band 36 and the lump body 46, this space 48 becomes the escape of the fluid to generate the resonance of the fluid, and the increase of the spring constant is suppressed, and the damping performance is also improved.

Title: Signal level detection circuit
Inventor: TAKATANI NAOKI
IPC: G01R19/165
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To allow a comparison reference value to be set over supply voltage by including a diode connected to an input terminal, two resistors connected in series from the diode to a power source and a means for detecting voltage at their common connection point. SOLUTION: When voltage Vin of an input terminal 1>= supply voltage (Vdd ), a diode D is cut off so that voltage at an output terminal 2 is 'L'. When the voltage Vin drops to a negative value less than 0V, and resistors are set so that R1>R2 and voltage at a node N1 is positive while it is higher than a threshold value of an inverter INV1, lower limit reference voltage (Vβ) can be set to negative voltage. At this time, when the input voltage Vin is Vin <=Vβvoltage at the output terminal 2 is 'H', while when Vin <Vβvoltage at the output terminal 2 is 'L'. Thus it is possible to detect whether V. >Vβ or not, and the reference voltage Vβcan be set at Vβ<0.
